Scrolling through pictures in iMessage is broken, again.

iPhone XS, iOS version 12.1.2

I recently wanted to find a picture that I sent to someone, so I tapped the info icon under the recipient's name in iMessage and started scrolling up through the pictures. If I scrolled up to the placeholder images, the view suddenly popped back to the top of the list after more images were loaded. This happened each time images were loaded into the scroll list. I see that this issue has been reported before. Anyone else seeing this again now?

P.S. I've already terminated the iMessage app and restarted my phone. Two other fiends are also seeing the same behavior, with different phones but the same iOS version.
